// January 2000 //
// //
// This class changes the interpretation of two PARAMETERs to a function //
// connects them to a single argument, with scale factors controlling how //
// the argument is increased before it is used to adjust the parameter. //
// In other words it makes a function like //
// //
// F(a_0, a_1, a_2; x) //
// //
// and reinterprets it as //
// //
// F(a_0; x, a_1) //
// //
